If I'm using one of these benders with a bending guide for 15mm copper pipe, do I still need to put a bending spring inside?
Modern pipe is so thin and the dies are soo poor its damn easy to ripple pipe. Sign of timesNo, but bend it slow or it can ripple
if you want to bend the copper easily without ripple even with a bender anneal it 1st it works a treat even on thin wall
I plumbed an old terrace house years ago, no pipework in the building at all. Customer said he would supply the copper pipe, Anyway it turned out to be schedule one grade, the walls were like tissue paper, couldn't bend at all, had to use fittings for everything, usual schedule three bends with no trouble, Do they still make the thin wall stuff?
Thanks for the replies, no need to buy a spring then and good tip about annealing it first

I've had a hell of a time with 22mm copper kinking recently while doing the new central heating work at home. I've tried everything from annealing it to bending as slowly as I can, I've polished the former and guides, oiled them everything! Still links like a ******* though.Dont waste your time annealing it, just use steady even pressure when bending

It's just poor quality pipe and I've tried all the different makes I can find round here.
Makes a simple job a real PITA!
